Summer CCMG '06 Agenda Abstracts The Speakers Connecticut Computer Measurement GroupSummer CCMG Membership Meeting Agenda Crowne Plaza (formerly Radisson Hotel), Cromwell - Thursday, June 8, 2006 ________________________________________ For the first time this millennium, CCMG will be hosting a conference day on Thursday. The Summer CCMG Conference is on Thursday, June 8th in Cromwell. It will be a day of reprise and response; virtual perspective and virtual behavior; work management and web management. There are six hand picked sessions that promise to answer your questions and excite your senses. We have an outstanding lineup, so join us and let us know what you think. The day begins with Glenn Anderson in the mainframe track reprising his discussion on WebSphere performance by bringing us up to date with the latest WebSphere Version 6 internals and tuning options. Ned Diehl is on the road and follows Glenn by bringing his award winning discussion on DB2 and response metrics. Over the wall, if you will, Pete Weilnau and Steve Marksamer begin the distributed track by sharing the stage and talking about real world experiences of a virtualized environment at a Fortune 100 insurance company. What is this strange new environment that every company with more than 10 servers is getting into? After this presentation your appetite will be whetted for a discussion on virtualization from the beginning of time. Yiping Ding and Ethan Bolker analyze the virtual possibilities. Throw what you thought you knew away and let them help build your faith once again. The afternoon sessions are just as strong with topics like ITIL and change;
Web management and customer expectations. Can’t get no satisfaction? Yes,
you can. It’s all there in Alistair Croll’s presentation which follows
Glenn Anderson right after lunch. If you stayed on the distributed track in
the morning and missed Glenn, you will be treated to his unique and engaging
presentation technique, this time on a different topic. Glenn will share his
discoveries in extending the WLM concept into the distributed world, and learning
how it should all come together … soon. This day will be a great way to
get the summer going. Come visit us; you will most certainly learn something
new. AGENDA

Agenda - AbstractsConnecticut Computer Measurement Group Summer CCMG Membership Meeting Agenda Crowne Plaza Hotel, Cromwell - Thursday, June 8, 2006 08:00-08:30 Registration and Coffee 08:30-08:45 Introductory Remarks Mainframe Performance Track 08:45-10:00 WebSphere App Server for z/OS Ver 6 Performance Tuning Glenn Anderson - IBM Training, Systems & Technology Group Now that you've installed WebSphere Application Server for z/OS Ver 6, how do you know that your system has been tuned for optimal performance? This session will provide performance tuning recommendations for WebSphere on z/OS, including application topology and configuration considerations, WLM settings, WebSphere tuning, JVM tuning, and z/OS system tuning. The session will also provide information about tools and techniques which can be used for performance analysis, such as RMF and the new ITCAM for Websphere. 10:00 - 10:15 Break 10:15-11:30 DB2 CPU and Response Metrics ** Best Paper Award, CMG 2005 ** Ned A. Diehl - Information Systems Manager, Inc. DB2 requests originate from a variety of diverse sources including batch, CICS, DDF and SAP. Related DB2 CPU usage can be recorded in RMF, DB2, SMF 30, and other subsystem records. Proper selection and interpretation of these values will vary with transaction source, DB2 environment, product levels, and analysis objectives. Analysts must be careful to include all desired values and avoid multiple counting of the same logical utilization. This paper will discuss the sources and analysis of DB2 CPU metrics and corresponding response times. Examples will include CICS, DDF, and SAP. Open Systems Track 08:45-10:00 Real World Adventures in Server Virtualization Steve Marksamer - Aetna, Inc. Pete Weilnau - Information Systems Manager Server Virtualization continues to be one of the hottest topics of 2006. Join our quest for enlightenment as we explore the performance data of a large enterprise environment. We will look closely at data captured from VMware ESX, its virtual machines and Windows servers seeking correlations between activity levels, response time and other key measurements both before and after virtualization. When our quest for enlightenment is complete, we will provide recommendations to aid in your virtualization endeavors. 10:00 - 10:15 Break 10:15-11:30 Virtual Performance Won't Do: Capacity Planning for Virtual Systems Ethan Bolker - U. Mass Yping Ding - BMC Software The history of computing is a history of virtualization. Each increase in the number of abstraction layers separating the end user from the hardware makes life easier for the user but harder for the systems capacity planner who must understand the relationship between logical and physical configurations to guarantee performance. In this paper we discuss possible architectures for virtual systems and show how naïve interpretations of traditional metrics like “utilization” may lead planners astray. Then we propose some simple generic prediction guidelines that can help planners manage those systems. We close with a benchmark study that reveals a part of the architecture of VMWare ®. 11:30-12:30 Lunch Combined Sessions 12:30-1:45 A Large Systems Guy Implements Enterprise Workload Manager (EWLM) Glenn Anderson - IBM Training, Systems & Technology Group Enterprise Workload Manager (EWLM) provides a way to monitor and respond to workload processing across multiple systems in a distributed heterogeneous environment. Now there are three words that strike fear into the heart of an old MVS guy - distributed heterogeneous environment! However, EWLM is an example of mainframe technology (z/OS WLM) migrated out to distributed platforms, so that is a bit comforting. This session will walk through the implementation and usage of the components of an EWLM domain. These include policies that define the expected performance; middleware equipped for ARM (Application Response Measurement), such as Websphere and DB2; and the EWLM Domain Manager that monitors, tracks and reports on performance against goals. 01:45 - 2:00 Break - Vendor Area Open - Raffle Drawings for Prizes (Be there to win!) 02:00 - 3:15 Using the Real User's Experience to Measure the Impact of Change in a Complex Web Environment Alistair Croll - Coradiant Software Measuring computer systems is essential for companies that want to anticipate problems and defuse them on a tactical timeframe. And it's also essential in building models of capacity that can anticipate demand. But many data center applications defy modeling. IT teams face trends like virtualization, dynamic provisioning, and distributed computing. All conspire to make a traditionally centralized, deterministic computing model hard to understand. As a result, engineering teams often make changes to content, applications, infrastructure and networks without fully understanding how those changes will impact end users and customers. Change impact management is a key step in any change lifecycle model. This session will look at Real User Change Impact Management in complex web-based environments. ________________________________________
